【摘要】 多胺是植物体内具有激素特性的生长调节物质,它们与生长素、细胞分裂素、赤霉素、乙烯和脱落酸5类植物激素具有密切关系。这5类植物激素可通过影响多胺的酶系统和前身物水平显著影响植物组织多胺水平及代谢;多胺也影响着植物组织中这5类激素的水平,并调节这些激素的生理作用。多胺与植物激素在作用方式及代谢特点上存在一定差别。更多还原

【Abstract】 Polyamines, plant growth regrulaters of Hormonal nature have close relations to five known plant hormones——auxins, cytokinins, gibberellins, ethylene and abscisic acid. The five plant hormones can significantly change polyamine content in plant tissues by affecting enzyme systems and precursor levels of polyamine. Polyamines,in turn,play important roles in regulating the levels and functions of these hormones.更多还原
